DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a down-story roofing material (hereinafter simply referred to as a "span roofing material") which is used as a decorative material and a connecting material when a down-story roof part is formed of a stepped roof material. ).

[0002]

2. Description of the Related Art Japanese Laid-Open Utility Model Publication No. 1-168621, Japanese Utility Model Laid-Open Publication No. 1-168622, and Japanese Patent Laid-Open Publication No. 1-2 are examples of this type of covering material for accommodating a descending corner building.
No. 90859, and the like.

[0003]

However, the above (1) to (4) are performed while hooking the corner ridge plate arranged in a substantially right angle to the roof material at both ends. A great skill is required in order to construct the board in a satisfactory manner, and there is a risk that water leaks due to variations in the construction, shifts in the flow direction due to external pressure such as snow, and in the worst case, falls. Furthermore, it is necessary to prepare separate corner ridge boards according to the change in roof slope,
Incurs an increase in equipment costs and costs for manufacturing equipment, etc.
There was a risk of confusion during construction.

[0004]

According to the present invention, in order to solve such a drawback, the left and right connections with the roofing material are strengthened by connecting with a waterproof joint material to enhance waterproofness, and are formed on the upper portion. The engaging tongue formed on the lower part is engaged with the engaging tongue and connected in the vertical direction, and in response to the change in roof slope,
By simply adjusting the length of the engaging tongue, it is possible to respond to changes in the roof slope with one kind of roofing material without using another roofing material separately. The present invention proposes a roofing material that has a decorative surface and has improved design, waterproofness, and workability.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of a roofing material according to the present invention. FIG. 1 is an explanatory view showing the roofing material. FIG. 1A is a perspective view showing a front surface portion, and FIG. 1B is a perspective view showing a rear surface portion. That is, the roofing material A is a metal plate (a color steel plate, an aluminum plate, a titanium plate, a stainless steel plate, a sandwich steel plate, a clad steel plate, or the like) or a synthetic resin plate formed by roll forming, press forming, or the like. As shown in FIG. 7, in the lower corner building of the roof, a plurality of roofs are laid for each step to function as a waterproofing material, a covering material, and a decorative material.

[0006] More specifically, the roofing material A is formed into a fan shape with a substantially semi-conical shape as a whole, and as shown in FIG. 2 which is an end view of a portion indicated by the II line in FIG. The cross section is formed in a mountain shape from the vertex 1a corresponding to the central portion of the decorative surface 1. Further, as shown in FIG. 3 which is an end view of a portion indicated by a roll line in FIG. In the lower part, a stepped decorative surface 4 bent to the back surface 3 side, a folded piece 5 having a tip of the step decorative surface 4 bent substantially parallel to the decorative surface 1, and a lateral center of the folded piece 5 The engaging tongue piece 6 is formed by extending the portion and projecting. Further, on both left and right edges of the decorative surface 1, goby-shaped fitting tongue pieces 7 bent in three directions on the back surface are formed.

[0007] The shape of the vertical section of the decorative surface ₁ is substantially the same as the shape of the wood opening of the decorative surface B1 of the roofing material B for stepping roof as shown in FIG. Part B ₂
In order to achieve a moderate level difference and improve the design.

The locking tongue 2 engages with and engages with the engaging tongue 6 to connect the turning material A up and down to eliminate flapping of the turning material A and to position the turning material A located at the top.
The folded back piece 5 is in close contact with the upper part of the decorative surface 1 of the roofing material A located at the lower part and exhibits waterproofness.

Further, Kakarigoshitahen 6 as shown in FIG. 4 (a) ~ (c) , is to change also the length l ₃ corresponds to the gradient of the roof. That is, longer large enough length l ₃ greater the angle of slope of the roof, smaller the length l ₃ the smaller the angle of the slope is to shorten. That is, if the gradient angle increases, the angle θ _{1 of the} vertex 1a shown in FIG.
Small Kunar is. (Note that turning roofing material A can follow easily theta ₁ changes by utilizing the elastic deformation of the material.) To intersection with it with Figure 1 eaves line and downlink building line
That angle θ ₂ of the hem point 1b is actually the corner The higher the gradient is
This actual angle, even though the degree must increase
And the skirt point 1b is shifted toward the eaves as a whole. Therefore the length l ₃ is shorter and locking tongues 2 engage with Kakarigoshitahen 6, no longer engaging, or with butter, the risk or to fall off is increased. Therefore, it is intended to advance Kakarigoshitahen leave longer formed length l ₃ of 6 to cut in response to the slope of the roof at the factory shipment. In this way, since the roofing material A can respond to a change in roof slope with one type, costs such as manufacturing equipment and costs can be reduced.

The fitting tongue 7 is used to connect the roofing material A and the roofing material B using a waterproof joint material C as shown in FIG. That is, the fitting tongue B ₃ of the roof material B is attached to the left and right connecting tongues C ₁ and C ₂ formed in a goby shape on the waterproof joint material C.
And the fitting tongue piece 7 of the roofing material A is inserted, locked and connected. According to such a procedure, the upper, lower, left and right directions are connected, and the roof foundation is sequentially constructed from the eaves direction to the ridge direction.
It forms a corner ridge like this.

Here, the dimensional relationship will be briefly described.
As shown in FIGS. 1 (a) and 1 (b), the length of one edge of the decorative surface 1 of the roofing material A is l ₁ , the length of the locking tongue 2 is l ₂ , and the length of the engaging tongue 6. of the l _{3, 2} the angle of the foot point 1b theta, ₁ the angle of the vertex 1a theta 2, 5, the length l ₄ decorative surface B ₁ of roofing material B, a waterproof joint member 6 Assuming that the length of C is l ₅ , l ₁ ≒ l ₄ <l ₅ , l ₂ = 10
30mm position, l ₃ is when the roof slope is 2 cun 5 minutes 5-25
mm, the roof slope is about 10 to 30 mm when the dimension is 3 minutes and 5 minutes,
The roof slope is about 15 to 35 mm when the size of the roof is 4 × 5 minutes. θ
₁ and θ ₂ are derived from Equations 1 and 2. Note that n in Equations 1 and 2 is a dimensional gradient angle.

(Equation 1)

(Equation 2)

What has been described above is merely an example of the roofing material for a descending corner building according to the present invention, and a half-pyramid-shaped roofing material A as shown in FIGS. 8 (a) and 8 (b). Can be.

[0013]

As described above, according to the turning material for a descending corner ridge according to the present invention, the turning material comprises upper and lower locking tongues,
Since the fitting tongue and the right and left fitting tongues are fitted and locked, the fixing is strong, there is no flutter, and the waterproofness is high.
Since fixing tools such as nails are not required at all for fixing the roofing material, workability is improved, and the fixing tools do not appear on the appearance. When roofing is finished, a moderate step similar to that of the roofing material appears, and the appearance is improved. Only by changing the length of the engaging tongue, one kind of thatch can cope with a change in the slope of the roof, so that costs such as manufacturing equipment and costs can be reduced. There are features and effects such as.
